Enhancement-mode gallium nitride (GaN) transistors have been commercially available for over five years. Commercially available GaN FETs are designed to be both higher performance and lower cost than state-of-the-art silicon-based power MOSFETs. This achievement marks the first time in 60 years that any technology rivals silicon both in terms of performance and cost, and signals the ultimate displacement of the venerable, but aging power MOSFET.
